How to retrieve MongoDb collection validator rules?

Question

On MongoDB 3.4.4 I\'ve created a collection with a validator, but now some inserts fail this rules and I can\'t understand why.

1. Is there a way to output the rules

1. You can see the validation rules (among other collection information) with db.getCollectionInfos() for all collections or db.getCollectionInfos({name: "myCollection"}) for a specific collection: MongoDB docs
